These are Black Diamond Ascension Nylon STS climbing skins in the 140 mm width. They use nylon plush and Black Diamond's adjustable STS tail.

What it's for

Climbing skins stick to your ski bases so you can walk uphill, then peel off for the descent. Black Diamond describes the Ascension as a durable, grippy skin for daily backcountry use.

How it works

Nylon plush: Black Diamond describes Ascension nylon plush as durable, with strong climbing grip and efficient glide

STS tail: an adjustable tail attachment that lets one skin fit a range of ski lengths

Tip loop: a loop at the front hooks over the ski tip

Compatibility

• Width: 140 mm at the widest point of the skin
• How to check yours: measure your ski at its widest point. The skin should be as wide as that point or a little wider, then trimmed to the ski's shape
• Length: the length range for this unit is not in the listing. Check the box label against your ski length
